## Description

Size:998




























Port is a highly effective, yet environmentally smart product for completely eliminating odors in septic, RV and marine holding tanks, or anywhere there is odors due to decomposition such as dumpsters, RV dump stations or animal carcasses. Port also helps to decompose and break down solids and clear septic system drain fields, making your septic system more efficient and greatly extending the time between pumpings. Port is better than its competition for a number of reasons: 1. This is a green product. Unlike many of our competitors products, which are based on enzymes or formaldehyde, our powerful product gets rid of odors and breaks down solids but is also beneficial for the environment. 2. Works better than anything else. Originally designed over two decades ago for use in wastewater treatment plants and sewage systems, this powerful product encapsulates all the Hydrogen Sulfide, Ammonias and other odor causing substances. Port eliminates all odors while greatly accelerating decomposition. 3. Easier to use than any other product. For septic tanks with a drain field simply pour in 8 ounces of Port Monthly in a 500 gallon septic tank for routine maintenance. For problematic systems, 1 gallon of OP Port monthly in a 500 gallon tank will resolve most issues within a couple of applications. 4. Less expensive to use. Port is competitively priced with our competition, but over time you will use so much less of this product that you will experience significant savings. 5. Flexible for many uses. Besides Septic Systems, Port can be used in pit and composting toilets, RV dump stations, and wastewater lift stations. It can clear clogged drain fields in septic systems. Diluted 1:7 with water, it can be used to solve any biological odor issue including dumpsters and organic spills. 6. Proven in the field. Port is used extensively by the National Park Service, Forest Service, and Bureau of Land Management to eliminate odors in campground vault and pit toilets.
